A famous quote written by Mark Twain (圖)

The coldest winter I ever spent was a summer in San Francisco.  - Mark Twain.

Samuel Langhorne Clemens (November 30, 1835 – April 21, 1910), better known by his pen name Mark Twain, was an American humorist, novelist, writer, and lecturer.

It is not that summer in San Francisco is colder than winter in other cities. It is the unexpected chilly wind that makes people feel a lot colder when they expect a warmer summer weather in San Francisco.  In fact, San Francisco weather is generally very mild as compared with other cities in US.

By the way, I lived in San Francisco for almost 5 years and I love San Francisco.   Many fond memories were still with me as of today.
